OUTCOME COMPETENCIES:
The student will be able to describe the diversity in adaptation that occurs in
invertebrate organisms both anatomically and physiologically.
Laboratory exercises will enable the student to classify invertebrate species through
the use of taxonomic keys and the dissection of representative organism of the major
phyla.
The student will be able to identify the unique characheristics of invertebrate
organisms living in marine, freshwater, and terrestrial environments.

University Grading System:
A = 90 - 100
B = 80 - 89
C = 70 - 79
D = 60 - 69
F = BELOW 60
I = INCOMPLETE +
W = WITHDRAWAL
+ A grade of incomplete is changed if the deficiency is made up by midterm of the next
regular semester, otherwise, it becomes an "F". This grade is given only if
circumstances beyond the student's control prevented completion of work during the
semester enrolled and attendance requirements have been met.
ATTENDANCE POLICY:
Students are expected to make class attendance a priority. All absences must be
explained to the instructor who will decide whether the work missed may be made up.
An absence will be recorded when a student fails to return after an allowed break time
during the process of an extended class. Any student who misses 25% of scheduled
class meetings may be dropped from the course.
No make-up exams shall be given unless arrangements are made in advance of
foreseen absences. Emergencies accepted.
NOTE:
It is the university policy that no otherwise qualified disabled person be excluded from
participation, be denied benefits of, or be subject to discrimination under any educational
program or activity in the university. Student should inform the instructor of existing
disabilities at the first class meeting.
